Article Abstract

The presence of colorectal cancer stem cells (CSCs) have been associated with tumour initiation and resistance to therapy. This study investigated the co-expression and prognostic significance of the CSCs biomarkers CD44 and CD133 with wild-type EGFR (wtEGFR) and EGFRvIII in colorectal cancer (CRC). The expression of these biomarkers were determined in tumours from 70 patients with metastatic CRC by immunohistochemistry, and in a panel of human CRC cell lines, and their variants with acquired-resistance to EGFR inhibitors, by flow cytometry. The expression of CD44, CD133, wtEGFR and EGFRvIII were present in 17%, 23%, 26% and 13% of cases and the co-expression of CD44/CD133 with wtEGFR and EGFRvIII were present in 9% and 3% of the cases respectively. Only co-expression of CSCs/EGFRvIII ( = 0.037), and amphiregulin ( = 0.017) were associated with worse overall survival. Interestingly, disease-free survival was improved in BTC expressing patients ( = 0.025). CD133 expression and its co-expression with CD44 were associated with primary-resistance to irinotecan and acquired-resistance to anti-EGFR inhibitors respectively. Our results suggest co-expression of CSCs and EGFRvIII could be potential biomarkers of worse overall survival and resistance to therapy in patients with mCRC and warrants further validation in a larger cohort.

FASN promotes the stemness of cancer stem cells and protects colorectal cancer cells from ferroptosis by inhibiting the activation of SREBP2.

Introduction: Fatty acid synthase (FASN) is a key regulator of lipid metabolism, but its role in colorectal cancer (CRC) stemness and ferroptosis remains unclear.

Methods: FASN expression in CRC was analyzed using TCGA data and validated in CRC cell lines (CACO-2, HCT116, SW480) and normal HIEC-6 cells via qRT-PCR and Western blot. HCT116 cells (highest FASN expression) were used for experiments.

Chronic infection is a major contributor to gastric disease progression, with its involvement in autophagy and stem cell dynamics playing a critical role in disease mechanisms. This study investigated how . , particularly in combination with the carcinogen N-nitroso-N-methylurea (NMU), disrupted autophagy and stem cell function, driving gastric pathology.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy characterized by poor prognosis, strong resistance to therapy, and a dense immunosuppressive tumor microenvironment (TME). A small subset of cells known as cancer stem cells (CSCs), or tumor-initiating cells (TICs), are increasingly recognized as key contributors to tumor initiation, metastasis, immune evasion, and treatment failure. These cells are defined by their self-renewal capacity, plasticity, and resistance to chemotherapeutic and targeted therapies.

: Glioblastoma multiforme (GBM) represents one of the most aggressive and lethal primary brain malignancies, characterized by rapid proliferation, extensive invasiveness, and a dismal prognosis. Emerging evidence implicates nucleotide-binding oligomerization domain-containing protein 2 (), an intracellular pattern recognition receptor, as a potential driver of GBM progression. This study investigates NOD2's role in promoting glioblastoma through its effects on the epithelial-mesenchymal transition (EMT) and cancer stem cell (CSC) markers.

Cancer ranks as the second leading cause of death globally and has surpassed cardiovascular diseases to become the primary cause of mortality in developed countries. Cancer stem cells (CSCs), which play crucial roles in cancer recurrence, metastasis, and drug resistance, have attracted significant attention in targeted therapeutic strategies. Aptamers, with unique three-dimensional structures capable of specifically recognizing the surface markers of CSCs, show promising potential in targeted drug delivery systems.
